摘要： A rotary Wankel type engine system is disclosed, wherein the crankshaft is supported by a center main roller bearing. The rotor apexes are sealed by two piece apex seals and by side seals. The engine system further includes an oiling system which permits oil flow through the center bearing and through lubrication passages in the engine rotor to provide a means for cooling the engine rotor under high loading conditions. Riblets are defined in the combustion face of the rotor to promote aerodynamic lateral stratified charge control to minimize atomized fuel charge loss to surface wetting before ignition.

摘要： A prime mover for transforming energy from the pressure form to the mechanical form. The prime mover comprises a pair of toothed rotors which engage one another so as to be self-timing. Each rotor has a first portion of relatively large diameter and a second portion of relatively small diameter, each of the portions extending approximately 180.degree.. The rotors are enclosed in respective intersecting cylindrical chambers in a housing, with the tips of the teeth of the small diameter portion of each rotor being displaced radially inwardly from the peripheral surface of the corresponding chamber, and with the tips of the teeth of the large diameter portion of each rotor being directly adjacent to the inner surface of the corresponding chamber. First and second sealing members are mounted in the housing, and these engage the tips of successively passing teeth of the large diameter portion of each rotor, as the rotors turn. A drive fluid is introduced into an inlet in the housing located at the common tangent of the two rotors, and the drive fluid exits through a diametrically opposed aligned outlet.

摘要： In the preferred embodiment, the invention comprises a sealing arrangement in which an elongated slat-type seal is provided for slidable engagement within the slot of a rotor (such as a Wankel engine-type rotor, or the rotor in a vane-type compressor) and includes a leaf spring for biasing the seal outwardly from the slot to effect fluid sealing externally of the rotor. The leaf spring and seal have special, mutually-engaging keying configurations, and the spring has particularly determined contact points which maintain all possible biasing force therein for the longest service time thereof.
